How can you experimentally show how to purify a given sample of ammonium chloride by sublimation?
Take the given sample of ammonium chloride in a china dish.Place the china dish on a tripod stand for heating.Place the perforated asbestos sheet over the china dish.Place an inverted glass funnel on the asbestos sheet.Heat the china dish on a low flame.The vapour formed gets deposited on the inner walls of the walls of the funnel.Scrap the crystals with a knife.The crystalline substance so obtained is pure ammonium chloride.

How do you purify solid organic compound?
Many methods exist: precipitation and filtration, distillation, dissolution and recrystallization, sublimation, sedimentation etc.
What process could be used to purify potassium chloride?
Crystallization/recrystallization process can be used.
What is use of sublimation process of chemistry?
Sublimation is the act of turning an molecule from its gaseous state directly to its solid state. A commonly used example is the sublimation of carbon dioxide gas (CO2) into 'dry ice'. In the sublimation process, desiccation, or the removal of water, also occurs. (Hence the nickname 'dry' in dry ice) Although food products are not made from the process of sublimation, foods can be shipped with sublimed products (e.g. dry ice) in order to allow longer periods between packaging foods and cooking them.
What is the purpose of the sublimation and recrystallization steps?
Recrystallization and Sublimation are two commonly encountered methods of Purification. Several of these are done in the laboratory to obtain a pure sample of a particular organic compound. Recrystallization literally means to crystallize again. Sublimation involves heating the compound at low pressure from one apparatus and and condensing it in another. This is quite the same as distillation but of solid state.
What are the differences between column chromatography and sublimation in terms of their principles and applications?
Column chromatography separates compounds based on their different affinities for a stationary phase, while sublimation separates compounds based on differences in their volatility. Column chromatography is commonly used in purifying mixtures of compounds, while sublimation is often used to purify solids that can sublime.
Why is it impossible 2 purify benzophenone through sublimation method?

How would you separate and purify constituents of mixture of salt of iodine?
To separate salt and iodine, you can use sublimation. The iodine will sublimate at room temperature, leaving the salt behind. To purify the iodine further, you can re-sublimate it by heating it gently and collecting the vapor to form pure iodine crystals.
Why fused calcium chloride is used in the preparation of feric chloride?
Fused calcium chloride is used in the preparation of ferric chloride as a dehydrating agent. It helps to remove any water present in the reactants or products, ensuring the reaction proceeds efficiently. Additionally, fused calcium chloride can help to purify the ferric chloride product by absorbing impurities and moisture.
What is suspensoid readily precipitated by salts?
Gelatin is a common suspensoid that is readily precipitated by salts like ammonium sulfate. This process is used in food science and biochemistry to separate and purify proteins.
What is meant by differential ammonium sulphate precipitation?
Differential ammonium sulfate precipitation is a technique used to purify proteins based on their solubility in ammonium sulfate at different concentrations. By gradually increasing the salt concentration, proteins with higher affinity for ammonium sulfate will precipitate at lower concentrations, allowing for selective recovery and purification of target proteins from a mixture. This method helps separate proteins by exploiting differences in their solubility characteristics.
